  RT1547/PRC-126

is a "Squad-Radio", a radio operated with one hand for short range communication. Older well known examples for Squad radios are SCR-536/BC-611 (AM) from WWII or PRC-6 (FM).
The demand for a modern Squad Radio resulted in the development of the synthesized PRC-68, becoming the "father" of radios to follow: PRC-68A, PRC-68B, PRC-126, PRC-128, and PRC-136.
PRC-126 is a PRC-68 with frequency display and external frequency settability.
 
The antenna is matched by hand by means of switch. A wrong matching is shown by a beep-tone ( 1000 Hz ) A second beep tone ( 400 Hz ) shows a waek battery.
You can transmit and receive on the same or on split frequencies. By using a relais cable two PRC-127 form a relais.
 
Setting of frequencies:

  • Press SET- button and switch on
  • Press INCR- button until display shows the first number of the    frequency
  • Press SET- button to confirm this number
  • Use INCR and SET until the complete frequency is shown
  • Press SET once more to load the frequency
     
    From the beginning of the development to the PRC-126 , all American squad radios are shown in the museum.
